# Header

<!-- AURO-GENERATED-CONTENT:START (FILE:src=./docs/partials/description.md) -->
<!-- The below content is automatically added from ./docs/partials/description.md -->
The `<auro-header>` element is for rendering page or content headers without having to deal with font styling. Simply choose the level of the header you want and the style type.

The `<auro-header>` element is able to take any combination of options for heading levels and display options. See [Auro's header usage guidelines](https://auro.alaskaair.com/typography/usage) for additional examples sans web component dependency.

Defining the dependency within each project that is using the `<auro-header>` component.

<!-- AURO-GENERATED-CONTENT:START (REMOTE:url=https://raw.githubusercontent.com/AlaskaAirlines/auro-templates/main/templates/default/partials/usage/componentImport.md) -->

### Use CDN

<!-- AURO-GENERATED-CONTENT:START (REMOTE:url=https://raw.githubusercontent.com/AlaskaAirlines/auro-templates/main/templates/default/partials/usage/bundleInstallDescription.md) -->
In cases where the project is not able to process JS assets, there are pre-processed assets available for use. Legacy browsers such as IE11 are no longer supported.

```html
<script type="module" src="https://cdn.jsdelivr.net/npm/@aurodesignsystem/auro-header@latest/+esm"></script>
```

## Basic Example

<!-- AURO-GENERATED-CONTENT:START (CODE:src=./apiExamples/basic.html) -->
<!-- The below code snippet is automatically added from ./apiExamples/basic.html -->

```html
<auro-header>Hello World!</auro-header>
```

## Custom Component Registration for Version Management

There are two key parts to every Auro component: the <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes">class</a> and the custom element definition.
The class defines the component’s behavior, while the custom element registers it under a specific name so it can be used in HTML.

When you install the component as described on the `Install` page, the class is imported automatically, and the component is registered globally for you.

However, if you need to load multiple versions of the same component on a single page (for example, when two projects depend on different versions), you can manually register the class under a custom element name to avoid conflicts.

You can do this by importing only the component class and using the `register(name)` method with a unique name:

<!-- AURO-GENERATED-CONTENT:START (FILE:src=./docs/partials/customRegistration.md) -->
<!-- The below content is automatically added from ./docs/partials/customRegistration.md -->

```js
// Import the class only
import { AuroHeader } from '@aurodesignsystem/auro-header/class';

// Register with a custom name if desired
AuroHeader.register('custom-header');
```

This will create a new custom element `<custom-header>` that behaves exactly like `<auro-header>`, allowing both to coexist on the same page without interfering with each other.
